Brief introduction
- S11-M 20Kv series are new designed products particularly for 20Kv class power grid. The product can effectively improve electricity supply capacity, increase economic supply distance, conserve land use, and effectively reduce line loss. Product is labeled as energy-saving product by CMIF.
- S11-M 20kv series are designed for urban or rural area with high load density, region with rapid growth in electricity demand, and for emerging industrial zone with poor power grid development. The product is also suited for petrochemical plants, railway and mining industry, public place, substation etc.
